Hello everyone!
I hope someone know how and want to help me with my problem. I hope this doesnt seem too simple for you, It s just that i am a little bit uncertain.
I have writed G code myself and I wondered if its correct. I just want to make a thread with a mill using cylindrical interpolation in CNC lathe with driven tools. The mill is quite a small so I ll remove small amount of material just 0.1 mm. So i have to make several cuttings. the depth of threats is 1mm so its 10 cuts. When I program several cuts i quess I need to change cylinder radius notation. Here is an example Workpice radius=7.5mm and the depth of thread=1mm
T707
G97S3500M304M8
(first cut)
M52
G52C0
G28C0
G0X15C0Z0
G91G19Z0C0
G7.1C7.4 (this is what I wonder??)
G1G94Z0F60
X-0.2
Z-18.75C562.5
X5
G7.1C0
G95
G52C0
M53

(second cut)
M52
G52C0
G28C0
G0X15C0Z0
G91G19Z0C0
G7.1C7.3 (and again I wonder did I get it right here??)
G1G94Z0F60
X-0.4
Z-18.75C562.5
X5
G7.1C0
G95
G52C0
M53
G0G90Z0
and so on and so forth..
I dont have a postprocessor to do this. Can you tell me if this is correct???
Ill give any further information if needed..
Thank you very much!!
